Figure 1. — (A) Single-channel traces of gA5XB and the corresponding current amplitude histogram. (B) Single-channel traces of gA5XB after incubation with 1 μg/ml streptavidin added to both sides of a BLM and the corresponding current amplitude histogram. The BLM voltage was 50 mV. The solution was 1 M KCl, 10 mM Tris, 10 mM MES, 10 mM β-alanine, pH = 7.0. Planar bilayers were from DPhPC. The low-pass digital filter with a cutoff frequency of 53 Hz was used in these recordings.
